[DeTomaso] [Fwd: Re: oil???????]

[Dave Londry]

If you look at

http://www.mobiloil.com/USA-English/MotorOil/Files/Mobil_1_Product_Guide.pdf
you will find
- 1300 ppm of zinc in 15W50.
- 1100 ppm in 0W40 and 5W50
and 900 - 1000  in most of the rest

0W40 is probably an excellent oil for a modern engine.
